Given numbers are 893,289,665,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 893,289,665,646 is 18065390.
Find LCM of 893,289,665,646 with Prime Factorization
| 17 | 893, 289, 665, 646 |
| 19 | 893, 17, 665, 38 |
| 47, 17, 35, 2 |
Multiply the prime numbers at the bottom and the left side.
17 x 19 x 47 x 17 x 35 x 2 = 18065390
Therefore, the lowest common multiple of 893,289,665,646 is 18065390.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
893 x 289 x 665 x 646 = 110867298430
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
893 : 1, 19, 47, 893
289 : 1, 17, 289
665 : 1, 5, 7, 19, 35, 95, 133, 665
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 893,289,665,646, is 1.
Now, the common factors can be found like this.
893:19x 47
289:17x 17
665:5x 7x 19
646:2x 17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 19x 19 = 6137
Therefore, the value for common factors is 6137.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 110867298430/(1x6137)
LCM = 110867298430/6137
LCM = 18065390
Thus, we can understand that the LCM of 893,289,665,646 is 18065390.
